That may be why there aren't any real equivalents to Fox News on the left side of the political spectrum. (Note to Right Wingers who might want to respond the last point: you may want to rebut this, but I'll warn you off the bat that the correct answers won't include CNN nor MNBC.)
That's my observation as well. As correctly noted by NoNukes, we are all susceptible to confirmation bias. However, there still seems to be a modicum of self awareness and skepticism on the left that has nearly disappeared from the right side of the political spectrum. Commentators on MSNBC and CNN still present facts and don't cook up completely unsupported conspiracy theories like those see at Fox News. If there was someone like Alex Jones on the left, he would be laughed out of town and wouldn't have near the support that Jones has.
But I agree with your main point: it is pretty much hard to know what to do when 40% of the US voters will blindly continue to support Trump even as he covers the entire US with gasoline and sets it alight.
Sometimes you have to let the child burn themselves on the hot stove before they will learn their lesson. The real question is whether Trump supporters have the ability to even detect when they have been burned. It could also be that Trump supporters are so taken in by their tribalism that they will go down with the ship instead of simply admitting the truth.
